To all 'whom 'it may concern: p

Be it known that I, FRANK'J. PHILLIPS, a citizen of the United States,and resident of Chicago, in the county of Cook and State of Illinois,have invented certain new and useful Improvements in ElectromagneticSeparatore; and I do hereby declare that the fol owing description of myinvention, taken in connection with the accompanyin sheet of drawings,forms a full, clear, an exact specification, which will enable othersskilled in the art to which it appertains to make and use the same.

This invention has general reference to im rovements in electromagneticseparators; and it consists, essentially, in the novel and peculiarcombination of parts and details of construction, as hereinafter firstfully set forth and described, and then pointed out in the claims.

The object of this invention is the production of an eiiicient,serviceable, convenient, and comparatively inex ensive a paratus forseparating ferrous substances rom non-.ferrous met-als, and it isespecially designed for removing iron and steel from copper, brass,bronze, aluminum and similar turnings.

It is a Well-known fact that non-ferrous turnings such as are producedin machinesho s brass-finishing shops, and other estab ishments, containmore or less ferrous substances resulting from the wearA and breakage ofsteel too1s,- while operating on non-ferrous metals and also fromferrous articles being operated upon in the same machines in whichnon-ferrous goods are being produced. These mixed turnings, as they arecommercially termed, command generali a considerably lower price perpound t an those turnings from which the ferrous parts have beenremoved. By the employment of my electro-magnetic separator, I amenabled to remove from the mixed turnings all the ferrous matter at atrilling cost, so that the cleaned turnings will command the highestmarket price.

In the drawings already mentioned, which serve to illustrate thisinvention more fully, Figure 1 is an elevation of my improvedelectro-magnetic separator. Fig. 2 is a similar view of the same, the aparatus being turned at an an le of 90 egrees to that shown in Fi 1. i 3is a plan, and Fig. 4 is a sectionaview of a portion of the device, online w w of Fig. 2.

' movable Like Iarts are designated b correspondmg sym ols andcharacters o reference in al the res This e ectro-magnetic separatorcomprises an iron basket, A, which may be magnetized' by passing anelectric current through a coil located between the members of saidbasket, and which will demagnetize as soon as the electric current isinterru ted. This basket includesl two, forked mem ers 12, 13, which, bymeans of screws 14, are connected to an o long iron core 15, Fi 4, oneat each end. This core is surrounde by an insulation 16, and upon thisinsulator 1s wound the wire constitutin the coil 17, which winding issurrounds by an insulation 18, and the latter covered by a metallicjacket 19, to protect the coil from injury, said jacket being clampedtothe coil by screws 20, and retherefrom by removing 'said screws 20.

To the forked members 12, 13, there is secured a yoke B, by means ofscrews 21, which yoke terminates in a socket 22, which is internallyscrew-threaded to engage the similarly screw-threaded end of a tube C,which serves as a manipulating rod for this apparatus and to contain theelectroconductor that leads to the coil. On this tube C there is aswivel D, by which, and a rope 23, the apparatus may be suspended fromany overhead object to relieve the o p-l erator who 'actuates the same,from its weight.

On the upper end of the tube C there is located a switch-socket E, towhich an electroconductor F, is connected, while a continuation F, ofthis conductor F leads from the switch-socket E to the winding 17 of thecoil, and from the same, in the usual manner, the circuit beingcontrolled by the switch-button 24. The cord F is of sufficient lengthto con- Ilect to a source of electricity by the plug G,

Near the upper end of the tube C there is located a guard H, of anydesired design adapted to protect the switch socket at the upper end ofthe tube C when the apparatus is placed against the wall or otherobject, not shown.

In operation, this device is ushed into a heap of turnings and anelectric current sent to the spool or coil by turning the button 24.This w1l1 cause the magnetization of the forked members 12, 13, so thatany ferrous matter with which the tines 25 come in contact will adherethereto, and which will drop from? said tines as soon as the ap aratus'1s withdrawn from the turnings an the current turned off. The tines 25are inwardly bent at their lower ends and form, as it were, `a basketwhich will contain quite a bulk of the ferrous substance, it being afact that with an apparatus as described I have removed from a heap ofbrass turnings approximately 50 pounds of iron turnings at one picking.o

The entire apparatus is comparatlvely slmple, not liable to get out oforder, and very efficient in its actlon.

I am aware that changes in the details of construction of this apparatusmay be made without departing from the scope of my in vention.

Havinof thus fully described this invention, I cliim as new and desireto secure by Letters Patent of the United Statesl. An improvedelectro-magnetic separator, comprisln in combination, two members eachof w ich is provided with a series of tines, said members being spacedin parallel relation, the said tines belng inwardly bent and approachingone another, an electric coil interposed between said tined members,said electric coil havin an oblong core with which said tined mem rs arein conductive contact and to which said tined members are removablysecured, a box-shaped yoke secured to said tined members, said yokehaving an internally screw-threaded boss, a tube in screw-threaded engaement with said boss at one end, an electrlc switch at the other end ofsaid tube, an electroconductor connected to said switch, a furtherelectroconductor connected to said switch and passing through said tubeto saidcoil, a swivel on said tube, and an annular rim at the up er endof said tube, said coil being surroun ed by a jacket having its endsconnected by a fastening located in said yoke.

2. -An improved electro-magnetic separator, comprisin in combination,two members each of w ich is provided with a series of tines, saidmembers being spaced in arallel relation, said tines being inwardly ntand approaching one another an electric coil interposed between saidtined members, said electric coil havin an oblong core to the ends ofwhich sai tined members are removably secured and with which they are inconductive cont-act, a box-shaped yoke secured to said tined members,said yoke having an internally screw-threaded upwardly projecting boss,a tube in screw-threaded engagement with said boss at one end, anelectric switch at the other end of said tube, au electroconductorconnected to said switch, a further electroconductor connected to saidswitch and passing through said tube to said coil, said tube bem ofsuiicient length to permit its being use as a handle to push theapparatus over the ground, as set forth.

In testimony that I claim the foregoing as my invention, I have hereuntoset my hand in the presence of two subscribing witnesses.
